  • Coarse, anti-clogging sponge
  • Weighted base sinks instantly and helps prevent floating
  • Room to install air stone
  • Green components blend in with live plants

Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need is an air supply and you've got a filter that is fully contained within your aquarium.  Sponge filters are completely reusable, don't need any replacement cartridges and last for several years. Trusted by fish farms and wholesalers, sponge filters are a great choice for reliability and to set and forget.

The Aquarium Co-Op sponge filter is designed using coarse foam so that it can go many weeks between cleanings. The coarse foam with the weighted base means it'll stack on the bottom of your aquarium. No more floating up after a water change or initial installation. Green Plastic helps hide algae and blend in with your live aquarium plants.

Aquarium co-op sponge filter

I had a sponge filter in my tank already but it never seemed to work. so I ordered the aquarium co-op medium, with the air stone they suggested and it works perfectly. Also the price was about the same.

Great sponge filter

I put the air stone in the filter as recommended - love these. Have them in my 3 tanks!

One of the best!

I love this along with their special filter stones. It makes such a difference to my tanks. I may have to solely use these if Electric filter companies pull their replacement parts so that we have to replace our filter machines with new ones instead of just replacing parts!! And these are less messy to clean anyway. ;)
